Can anyone help me when I try to get my npc to spawn on a blood moon I got this error
c:\Users\Julian Romero\Documents\My Games\Terraria\ModLoader\Mod Sources\EpicnessMod\NPCs\BloodySlime.cs(38,24) : error CS0161: 'EpicnessMod.NPCs.BloodySlime.CanSpawn(Terraria.ModLoader.NPCSpawnInfo)': not all code paths return a value

Here is the npc's code

            npc.noGravity = false;

            npc.soundKilled = 6;
            Main.npcFrameCount[npc.type] = 2;
            npc.value = Item.buyPrice(0, 0, 30, 5);
            npc.buffImmune[BuffID.Poisoned] = true;
            npc.buffImmune[BuffID.Venom] = true;
            banner = npc.type;
            bannerItem = mod.ItemType("BloodySlimeBanner");
        }
        public override void NPCLoot()
        {
         Item.NewItem((int)npc.position.X, (int)npc.position.Y, npc.width, npc.height, mod.ItemType ("BloodGel"));
        }
    public override float CanSpawn(NPCSpawnInfo spawnInfo)
    {
  if (Main.bloodMoon)
{
return 1f;
}
    }

  
}
}

Your CanSpawn is only returning IF Main.bloodmoon is true, but it won't return anything if it is false. hence the error.
Make it an if else statement.

Well idk what you are doing, but you're now calling an if statement without even checking anything...

I don't know about you, but I'd look at some basic c# (csharp) tutorials if I were you. The method CanSpawn expects to return a float value, not a boolean. In your code, you're trying to return both types.

Code:

You are treating it like a method while it's actually a field/property, so you can just get; and set; it.
For example: music = 24;

Well, you can actually enter your world with mods, only it is not recommended, since multiplayer is not officially supported yet now. If you insist to play multiplayer with tmodloader, for now, it's gonna be bad, 'cause there will be a lot of bugs and wired phenomena which will disturb your game process.
